Interesting, although I don't fight this way when I ring fight, I didn't know that the US fought the English National team and I sure didn't know Terry Creamer beat then HWT World Champ Vic Charles. Creamer teaches Isshin Ryu in the St. Louis area and I remember attending a few of his tournaments a number of years ago. Here's the link.

None of it looks great to me, not this or the previous clip you posted. The techniques look sloppy and indecisive, their bodies often very off balance and their hands tend to drop to leave the face very open, the Shotokan guy a bit more so (and I sympathise because I have done it and I am pretty sure I looked much the same trying to score points). Yes it can encourage guts by having the nerve to go and face off against someone but is it really any practical use except as a sport in its own right? I would far rather watch Western or Thai boxing if I am looking to watch a fighting sport.

The problem comes not in the competition themselves, but when training changes to only reflect the competitions they enter. The value in such things is testing one's self. How many times do you hear of people touting their ability to drop people with their body strikes. I say if you can do so then enter a kyokushin tournament and prove that you can against someone other than your dojo buddies. Its about using what you train in a controlled environment. Its not the rules of point tournaments that are bad, its the way in which they are applied. If people only received points for striking a downed opponent the comps would look different. If "vigorous application" was truly a condition for earning a point then the tippy tap stuff seen in both open class and traditional karate tournaments would not count. Yes there is value in such things, but the value is not in winning a trophy or medal.
